EXPANSION-STANDARD TREE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 720,667, dated February 17, 1903.

Application filed October 18, 1901. Serial No. 79,180. (No model.) i

have invented a new and useful Expansion- Standard Tree-Support, of which the following is a specification.

7 My invention relates "to an expansion-standard tree-support, which consists of an iron clip in two parts bolted together, with two india-rubber clips for inclosing the tree, the said india-rubber clips being attached to the iron frames by springs. On one or both of the iron clips or frame I weld a short stem with square eye. This said eye receives the end of a stake, which is driven into the ground.

The object ofmy invention is to form an apparatus with an expanding center to allow trees to develop without chafing the stems,

, which is not done by the present mode of fastoning to stakes. I attain these objects by the mechanism illustrated in the accompany-' ing drawings, in which.

Figure 1 is a plan of the tree-clip with one square eye. Fig. 2 is a side View of Fig. 1. Fig. 3 is a plan of the apparatus with two square eyes. Fig. 4 is a section of the clip d, showing the recess g, in which the end of the spring 6 is fixed under the screw-head h. Fig. 5 is asection of the india-rubber clip on line A B. p

In carrying my invention into practice I construct of Wrought-iron (or malleable) a semicircular clip 0, and on this said clip 0 I weld a stem 6, with asquare eye a atits end. The eye a is provided with a nail-hole t' for fixing the end of the stake when passed into the square eye a from the ground. Each end j of the semicircular iron clip 0 is turned outward in a horizontal direction and is provided with a square hole is. To the abovedescribed semicircular clip 01 fix by boltsland nuts m another corresponding plain semicircular clip d with ends n. These said ends are provided with round holes 0. In the interior of the iron clips which form the frame I attach two semicircular india-rubber clips ff by means of springs. Each spring is attached at one end to the india-rubber, as shown by dotted lines, Fig. 1, with the other end fixed to the iron clip or clips by the screw 19 beneath the head It in the recess 9.

If preferable, I may adopt an apparatus as in Fig. 3,'having two semicircular-wroughtiron clips 0, with stems b and square eyes ato receive the ends of two stakes.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a tree-support, the combination of two semicircular metallic clips, having outturned ends, each provided with a square eye necting said outturned ends; two semicircular rubber clips, and springs connected to both sets of clips, and supporting the rubber clips within the metallic ones, substantially as described.

2. In a tree-support the combination of two semicircular metallic clips, having outturned ends, bolts and nuts for. connecting WILLIAM OARTWEIGHT.
